You have pretty good lead hip action, but there are some pretty obvious things I noticed.
Your “balance point” doesn’t allow for an effective weight shift. You are almost perpendicular at the peak of your leg lift, resulting in a late weight shift.
Your head and lead shoulder is not in an optimal position. This likely reduces your ability to locate pitches because your head is not in the center mass of your body.
At foot strike, your arm has still not reached the cocked position. In fact your arm is in almost a horizontal position, and this can put an incredible amount of stress on your shoulder.
Your achieving little, if any, hip to shoulder separation. This is a direct results of your late weight shift. Stop the video at :20 to see this
Last thing, I definitely think you can slow your mechanics down a little bit. While it’s true the faster you move, the faster you throw. This doesn’t imply you should speed up your mechanics to the point of of erratic.
Things you’re doing well:
- Keeping your lead hip closed
- Leading with the hip
- Your back leg drive is decent, but could definitely be better.
Focus on one thing at a time! Good luck
